Serving members of the Armed Forces will be entitled to free train travel on Sunday if attending Remembrance events.
All train companies in Britain are running the scheme for service personnel marking the centenary of the end of the First World War.
Operators are also offering free travel for Royal British Legion volunteers raising money through Poppy Appeal collections in Birmingham, Bristol, London and Manchester.
Paul Plummer, chief executive of industry body the Rail Delivery Group, said: "This centenary year, we remember those who worked tirelessly to keep Britain's railway moving during the Great War and the thousands of railway workers who served under arms."
Defence Secretary Gavin Williamson said:
"This year's remembrance is full of significance with the 100th anniversary of the end of the First World War, so I am really pleased that the men and women of our Armed Forces will be helped with their travel as they mark this event.
"Alongside the volunteers of the Royal British Legion, our people make an important contribution to the ceremony and solemnity of remembrance across the UK."
